Tunnelhouse ~ Greenhouses - NZ made "Built stronger to last longer"

We manufacture our tunnelhouses using sturdy 32mm box section aluminium to form the main hoop frames. Redpath tunnelhouses are 2.36 metres wide and come in eight different lengths.
Long-life clear Duratough commercial greenhouse film 210 microns thick is used for the covering which has a 10 year + service life.
You can purchase directly from our factory and will recieve a discount from the prices shown below when you use the shopping cart section, We then deliver direct to your door.
Our tunnel houses include a quality box section 60mm x 30mm aluminium base rail as standard so there is no timber to rot or steel to rust at the ground contact point. A single sliding aluminium door and rear 3 blade glass louvre window is also standard. Some of the longer length models include a roof vent and high wind kit. 
Redpath is New Zealands longest established commercial and domestic greenhouse manufacturer and we proudly manufacture these tunnelhouses to suit New Zealands climate - they are not a flimsy import!.  We keep a full stock of spare parts on hand if ever needed.
To save you time we deliver the tunnelhouse 50% assembled with both of the end walls made up, The louvre mechanism fitted, and the door frame also assembled.
